OF .OI-IIOAGO, ILLINOIS.

ROTARY BRUSH.

SPECIFICATION forming part of Letters Patent No. 462,156, dated October27, 1891.

Application filed January 27, 1891. Serial No. 379,250. (No model.)

To @ZZ whom t may concern:

Be it known that I, OLE PEDERSON, a citizen ot' the United States,residing at Moline, in the county of 'Rock Island, Illinois, haveinvented certain new and useful Improvements in Rotary Brushes, as setforth in the accompanying drawings, forming part of this specification,in which- Figure 1 represents a side elevation of a rotary brushembodying my invention. Fig. 2 is a sectional view of the same. Figs. 3and 4 represent details to be referred to.

My invention relates to rotary brushes generally, and particularly tothat kind employed in cleaning or abrading metal, stone, the.; and myinvention consists of the constructions and combinations of deviceswhich I shallhereinafter fully describe and claim.

To enable others skilled in the art to which my invention appertains tomake and use the same, I will now describe its construction and indicatethe manner in which the same is carried out.

In the accompanying drawings, A represents an arbor or shaft, the outerend of which is threaded to receive a nut d, for a purpose to behereinafter stated. Upon the arbor is fitted a sleeve B, which bearsagainst a shoulder l) on the arbor, and is held in place by the nut Ctbearing against the outer end of the sleeve or against an interposedwasher c, as shown in Fig. 2. Around the outer end of the sleeve are theradially-disposed rods C, convexly curved, as shown, and each having oneend fixed to the sleeve and the other end adapted to pass throughopenings in a disk D, fixed to the sleeve and to which said ends areriveted, headed down or otherwise secured, these rods forming links,staples, or pivots about which the holders of the abrading-brushes havea free swingingmovement.

These holders consist of sleeves or sockets E, into which is firmlysecured the wire or other abrading material which forms the brushesproper, and the inner ends of said sleeves or sockets are formed witheyes F, through which the curved rods C loosely pass, whereby saidholders have a free movement in all directions about said rods.

To hold the brushes in proper position and to adjust them so that thedistance between their outer ends may be varied to lcorrespond with thesize of the material or space operated upon, I employ a dished collar G,having a hub or sleeve II adapted to be mounted upon the sleeve B andadjustably held thereto by means of a set-screw d or analogous device.The outer end of this collar is dished or cup-shaped, and its innerperiphery at e is faced with wood, leather, or similar material 6o toact as a cushion and prevent unnecessary wear of the sleeves which carrythe tufts of abrading material. From this description it will be seenthat the brush revolves in a plane substantially parallel with the arborupon which it is tted, and that when in operation the centrifugal forcethrows the independent brushes outward, so that they have a bearingagainst the wood-faced inner surface of the collar G.

A brush constructed as herein described is especially adapted forcleaning those parts of metal castings impossible to reach with a brushwhose abrading material is not substantiaily parallel with the shaftwhich carries it. In other words, if the inside of a cast pulley and thearms and hub of the same are to be cleaned, it can only be done by handor by a brush substantially like the one herein shown and described.Again,by making the 8o collar G adjustable on its sleeve I am permittedto move it forward or backward, and thereby adjust the independentbrushes so that they may, when in operation, describe larger or smallercircles, according to the adjustment and the size of the space to becleaned.

This brush is also adapted for operating upon stone, wood, or any othersubstance Whose surface is to be cleaned or abraded.

Having thus described my invention, WhatI claim as new, and desire tosecure by Letters Patent, is-

l., The combination, with an arbor, of a sleeve thereon carrying aseries of independ- 95 ent brushes loosely mounted and adapted to bethrown outward by centrifugal force, and a collar adjustably mounted onsaid sleeve and adjusting the brushes, substantially as hereindescribed.

2. In a rotary brush and in combination with its arbor, a series ofindependent loosely- IOO mounted brushes carried by the arbor, and asliding piece for limiting the outward throW of the brushes,substantially as herein described.

3. In a rotary brush, the arbor and a sleeve mounted thereon, incombination with 'independent brushes loosely mounted on the sleeve in aplane substantially parallel Wit-h the arbor, and a collar adjustablysecured tosaid sleeve and having its outer end dish-shaped, so as toconfine the independent brushes and limit their outward movement,substantially as herein described.

4. In a rotary brush, the combination of tire arbor, the sleeve thereonprovided with the radially-disposed rods, the independent brushesloosely lmounted upon said rods, and

the dished collar surrounding the brushes' and limit-ing their outwardmovement, said collar being adjustably secured to the sleeve and havingits inner surface faced with Wood or analogous material, substantiallyas herein described.

5. In a rotary brush, the combination of.

the arbor, the sleeve thereon provided With the disk andradially-disposed curved rods, the independent brushes having socketsloosely mounted on the rods, and the adjustably-secured dished collarfor adjusting the brushes, substantially as herein described. OLEPEDERSON.
